Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate with an Admin API JWT (as above), then POST to /ghost/api/admin/newsletters/ to create a newsletter (name required)
Optionally pass opt_in_existing as a creation query param to auto-subscribe existing members to the new newsletter — verify current query-param support against your Ghost version before relying on it
Update sender name, reply-to, and design fields with PUT /ghost/api/admin/newsletters/{id}/
List existing newsletters with GET /ghost/api/admin/newsletters/ to get the slugs needed when publishing/scheduling a post to a specific newsletter
Pass the target newsletter's slug via the newsletter query parameter when publishing or scheduling a post through the posts endpoint
Known gotchas
On Ghost(Pro) sites without a custom sending domain, senderEmail is locked for deliverability/compliance and can't be freely edited via the API
The newsletters endpoint supports Browse/Read/Edit/Add only — there's no documented Delete; archive a newsletter instead
Bulk email delivery requires Mailgun (self-hosted) or is handled automatically (Ghost Pro) — creating a newsletter via API doesn't by itself enable sending if bulk email isn't configured
